摘要
针对QHD32-6油田大面积分布的河道砂体中存在单一河道砂体边界这种情况,在全区展开了单一河道砂体的追踪。主要利用研究区有限的测井、测试、取心及示踪剂等资料进行分析研究。根据砂体切割及平面匹配关系对复合砂体进行分类,从而有利于单一河道识别后对复合砂体内部连通关系的认识,为准确地判断油水井的注入或来水方向、剩余油分布等,为油田开发、增产工艺及措施的实施提供更准确的地质依据。
Large-scale distribution of channel sand bodies in QHD32-6 oilfield have single channel sand boundaries, and a tracking for single channel sand bodied is carried out.The limited data such as logging,testing,coring and tracers are used into the study and analysis.Composite sand body is classified according to the cutting and plane matching relationship of sand body,it is beneficial to the recognition of inner connection relationship among composite sand bodies after identifying single river channel,which provides accurate geological basis for determination of water directions of oil wells and remaining oil distribution and oilfield development and stimulation.
